Firstly, we need to find the gradient at this point on the curve as the tangent will have the same gradient. So to find the gradient of the curve or in other words, dy/dx, we differentiate the equation. T...

This is a typical mechanics question in an AS/A-level exam and uses the principles of SUVAT and projection.

• We can try to calculate the maximum height reached first using the veritical compon...

If you need to solve them, then you just plug your way through the algebra to get to the answer.

In this question (Q7) you need to find the value of a constant such that there is no solution to the...

the linear speed of an orbiting body is given by the equation sqrt(GM/2r) where M is the mass of the attracting body, G is the gravitational constant and r is the distance between the two bodies' centres ...

The Young's modulus is a measure of the stiffness of the material - higher the young's modulus, higher the stiffness. It is calculated by dividing stress by strain over the elastic deformation region and ...
